Multicell electric storage battery

A multicell electric storage battery, which comprises a container of generally right prismatic shape and including a top and bottom, closed at the top by means of a lid through which a plurality of connecting terminals protrude, which container is subdivided internally into two or more cylindrical cells including cylindrical walls and housing positive and negative electrodes segregated by intermediate separators, wound in a spiral shape, said positive and negative electrodes creating different polarity leads for adjacent cells, characterized in that the battery comprises vertical throughpassing conduits that open through the lid and the bottom and are disposed among adjacent cells, such conduits are intended for the circulation of air or another coolant and for the passage of threaded rods for anchoring the battery to a mounting tray or a soleplate;

• and in that the cylindrical walls of the cells comprise a planar upper segment common to adjacent cells, the planar upper segment includes an access opening through which an electrical connection is made between said different-polarity leads of said adjacent cells.
